[ http://issues.apache.org/jira/browse/MYFACES-884?page=comments#action_12358714 ]
Mike Kienenberger commented on MYFACES-884: ------------------------------------------- Hmm. I thought I had submitted a patch to update the dataScroller docs when I had the same problem. I'll make sure to change it right now. > dataScroller "divide by zero" error should be changed to a "missing row > attribute" error > ---------------------------------------------------------------------------------------- > > Key: MYFACES-884 > URL: http://issues.apache.org/jira/browse/MYFACES-884 > Project: MyFaces > Type: Improvement > Components: Tomahawk > Versions: Nightly > Environment: Tomcat 5.5.x > jdk 1.5.0_05 > Tiles (struts 1.2.8) > Reporter: Steve Franson > Assignee: Mike Kienenberger > Priority: Minor > > When using the t:dataScroller inside of a t:dataTable, I get the a "/ by > zero" exception. Tracing into it, it looks like it is trying to get the page > index from the getRows() of the UIData of the table, which comes back as 0 > (but still displays all of the rows without the scroller in it), and then > trys to do a % using zero. > This might be related to MYFACES-820 as we are both using the tiles > integration. > Full stack trace: > java.lang.ArithmeticException: / by zero > at >
